Kawasaki Ridge 6" Portal Gear Lift

GDP Portals Turn Your Ridge into a Powerhouse
Your Kawasaki Ridge hasn’t reached its full potential—that is, until you’ve install GDP Portals. SuperATV’s 6” Portal Gear Lift gives you a lift and gear reduction in one package. They come in a cast or billet aluminum housing with a choice between a 30% and 45% gear reduction. You’re able to fit up to 33” tires while conquering tough terrain.

Conquer Tough Terrain
GDP Portals will give your Kawasaki Ridge the power it needs to tackle any terrain. If you’re riding through mud, rock crawling, or running larger tires, you’ll want a 45% gear reduction. To keep your top speed while still boosting torque, a 30% gear reduction is the best choice.

Keep Your Drivetrain Safe
Adding more power to your Ridge is great—until it puts stress on your drivetrain. That’s where our 6” Portal Gear Lift comes in. The gear reduction is in the wheel hub instead of the transmission. So your axles, prop shaft, differential, and transmission will be safe because there will be less strain on them. You’re getting all that power without having to stress about damage.

GDP Portals Are Built to Take a Beating
We designed GDP Portals to be as tough as your Ridge. From billet aluminum housings to heavy-duty 5/16” steel alloy backing plates, every piece is made to handle serious abuse. Ride hard and push limits—these portals can take it.

• Our housings are reinforced for gear retention and optimized for oil flow
• Advanced steel alloy backing plates are stronger than chromoly
• Enhance with Portal Blood—gear oil formulated for GDP Portals
• There are no gimmicks and no vents because vents do more harm than good—we know because we tested them

• Advanced gaskets and O-rings with excellent oil resistance and low deterioration rates
• A sealed input gear and double-lipped output seal
